Diapycnal Nutrient Fluxes and a Practical Assessment of the Biological Nutrient Trap in the North and South Atlantic Subtropical Gyres

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Diapycnal mixing supplies nutrients to the euphotic zone, which in oligotrophic regions may substantially support rates of new production. However, the consensus view that diapycnal nutrient fluxes support new production within the entire euphotic zone is challenged by deep living autotrophs that likely consume some, if not all, of the ...

Structuring of bacterioplankton communities by specific dissolved organic carbon compounds

Environmental Microbiology, 2012
Summary The main role of microorganisms in the cycling of the bulk dissolved organic carbon pool in the ocean is well established. Nevertheless, it remains unclear if particular bacteria preferentially utilize specific carbon compounds and whether such compounds have the potential to shape bacterial community ...

Active bacterioplankton community response to dissolved ‘free’ deoxyribonucleic acid (dDNA) in surface coastal marine waters [PDF]

, 2018
Seawater contains dissolved ‘free’ DNA (dDNA) that is part of a larger <0.2 μm pool of DNA (D-DNA) including viruses and uncharacterised bound DNA.

Aotearoa New Zealand’s marine carbon cycle in a changing climate – Current understanding and future directions

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 913-956, December 2025.
ABSTRACT The marine system plays a critical role in the global climate cycle, as a major control of atmospheric carbon dioxide (CO2). Marine primary production (photosynthesis) and remineralisation of organic carbon (respiration, degradation) determine the amount of CO2 sequestered in marine sediments and deep‐water environments on century to ...

Impact of environmental factors on bacterioplankton communities

, 2016
In the scope of the present thesis, next generation sequencing, assessment of bacterial bulk parameters and interdisciplinary approaches were used in laboratory experiments and field studies to add to current knowledge on the impact of important environmental factors on bacterial communities.

Influence of coral and algal exudates on microbially mediated reef metabolism. [PDF]

, 2013
Benthic primary producers in tropical reef ecosystems can alter biogeochemical cycling and microbial processes in the surrounding seawater. In order to quantify these influences, we measured rates of photosynthesis, respiration, and dissolved organic ...

Impact of Submarine Groundwater Discharge on Microbial Communities in a Highly Anthropized Coastal Lagoon (Mar Menor, SE Spain)

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Submarine groundwater discharge (SGD) supplies large quantities of nutrients and other terrestrial elements to coastal ecosystems, impacting marine biota and ecosystem functioning. Despite the relevance of prokaryotes for marine biogeochemistry, little is known about their responses to groundwater inputs.

Phytoplankton Communities Exhibit a Stronger Response to Environmental Changes than Bacterioplankton in Three Subtropical Reservoirs. [PDF]

The simultaneous analysis of multiple components of ecosystems is crucial for comprehensive studies of environmental changes in aquatic ecosystems, but such studies are rare.

Beyond the Meal: Trophic Controls by Pelagic and Demersal Chondrichthyes in Two Different Mediterranean Marine Food Webs

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Pelagic and demersal sharks played different top‐down controls in the food web. Pelagic sharks act as apex predators impacting mesoconsumers. Trophic controls patterns by demersal sharks change according to ecosystem traits. ABSTRACT Pelagic and demersal Chondrichthyes can assume different patterns of trophic controls on marine food webs, sustaining ...

Microbial respiration, the engine of ocean deoxygenation [PDF]

, 2019
Microbial plankton respiration is the key determinant in the balance between the storage of organic carbon in the oceans or its conversion to carbon dioxide with accompanying consumption of dissolved oxygen.
